Came across this video on uTube which talks about the JMI amps and the Music Ground scandal that JMI became embroiled in and distanced itself from. The JMI AC30 is probably one of the closest you could find to the 60's AC30.
But it also brings up how difficult it is now to find a VOX amp or clone that does the original tones. Most of the clones out there are variations of the AC30 sound and not the sane deal. Build quality by VOX has often been lacking and even the Top Boost tone circuit messed with. For some reason VOX does not seem interested in making the amps that gave the brand its legendary status.
You would think VOX would want to show off its true heritage by manufacturing modern day examples of its legendary amps ?
